WATER- METER.

SPECIFICATION forming part of Letters Patent No. 237,677, dated February15, 1881.

Application filed July 1, 1880.

T 0 all? whom it may concern.-

Be it known that I, JAMES B. CURRY, of the city of Louisville, in thecounty of J efferson and State of Kentucky, have invented a certain newand useful Im provement in Meters for Measuring the Water Delivered toCustomers by Water Companies; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same,'r,eference being had to the accompanyingdrawings, formingpart of this specification.

This invention relates to a new and novel improvement in cylinderwater-meters, consisting, first, in a cylinder and side pipe, withreceiving and discharge openings similar to a steam-engine, connectingwith a receivingchest on the side pipe, the faces of which openings aredressed ofi perfectly true and covered with a sliding valve, to which areciprocating motion is given by the pressure of the water as it entersthe different ends of the cylinder alternately, where it is measured bythe capacity of the cylinder at each stroke, and the number of gallonsregistered by means of a device similar to a clock or gas-meter. Thismachine is operated by the pressure of the water acting upon a detachedpiston-head in the cylinder, which moves it back and forth, and in sodoing it strikes the end of the pistonrods and thereby gives motion tothe frame or yoke on the outside, which further transmits motion to anarm working loosely on the receiving-pipe, the upper end of which arm ismade somewhat in the form of a quadrant with a flange on the in side,having a long slot through it to admit the end of another lever thatworks loosely on the receiving-pipe, and to which an adjustable weightis secured for the purpose of overcoming the dead-points in thevalvemotion by suddenly turning down after passing the perpendicularpoint, and in its descent strikes the end of a curved lever behind itand presses it down to a stop-lug on the cylinder. This curved lever isalso made to work loosely on the receiving-pipe, and by means of acograck in the center, and a corresponding rack on the end of the armthat works the valveshaft in the chest, motion is transmitted to opcratethe valve in either direction by the oscillation of the weight, as itturns back and (No model.)

forth by means of the pressure of the water entering the ends of thecylinder alternately, as the head moves from one end to the other andthe water passes out.

The object of this my invention is to provide a meter for measuring thewater delivered to consumers by. water companies, that will be reliable,durable, and convenient in its operation, and at the same time requirebut little room to contain it while in use. I attain these objects bythe mechanism illustrated in the accompanying drawings, in which- Figurel. is a perspective view of the machine, showing its generalconstruction. Fig. 2 is a sectional elevation taken, as indicated, at XX, showing the detached piston-head, receivin g and exhaust openings,and slide-valve mechanism. Fig. 3 is a plan view of the cylinder,showing the side pipe, receiving and discharge openings, and frame onthe outside. Fig. 4 is a sectional view taken at Y Y, showing theopenings and valve mechanism in the chest. Fig. 5 is a plan view,showing the curved lever that gives motion to the valve and the weightthat operates it, with the lugs on which it falls. Fig. 6 is a flatview, showing the lugs, edge of the yoke, and arm that operates theweight.

Similar letters refer to similar parts throughout the several views.

This my invention will be more fully illustratedin detail in thedrawings, in whichA repthe required size, and bored out on the insideperfectly true, similartoasteam-cylinder. B is the side pipe, which ispermanently connected with the cylinder. 0 O are the openings connectingwith the cylinder. D is the receiving and E the discharge openings. F isthe valve-chest, and G is the slide-valve that covers the openings, andby its reciprocating motion causes the water to enter the ends of thecylinder alternately. H is the arm, and I is the shaft by which it isoperated. J is a detached piston-head, working loosely in the cylinder,but packed so as to be water-tight. K K are the packing-followers. L isthe bolt by which they are closed up. N N are short piston-rods in theends of the cylinder, connecting with the frame 0 on the outside, bywhich motion is given to arm P, which works resents the cylinder, whichis made of metal, of v loosely on the receiving-pipe, and by which motion is further transmitted to operate thewei ght Q by thequadrant-shaped head S, which has a flange on the inside, with aslot-opening sufficiently long to admit the lever B, which also worksloosely on the receiving-pipe, and to which the adjustable weight Q, issecured, and by which motion is given to curved lever T by catching theprojections u a 0n the side, in its descent downward, until it rests onlugs U U. At each turn of the weight, and by means of a small cog-rack\V, in the center of lever T, and a corresponding rack on the end of armA, motion is given to the shaft I and arm H to operate the valve G inthe chest F.

Therefore, having thus fully described the nature and object of myinvention, its operation is simply that of connecting the machine withthe water-pipes, and by means of the pressure the water will enter thecylinder and press the movable head up against the end of thepiston-rods connected with the sliding frame on the outside, and therebytransmit motion to the several devices that operate the slide valve inthe chest, causing it to move back and forth, and thereby permit thewater to enter the ends of the cylinder alternately, and when full passout, similar to the escape of steam in a steam-engine.

1 am aware that some parts of this machine are made similar to those ofa steam-engine, but greatly outof proportion. Therefore I do not claimsuch combination of parts, broadly; but

What I do claim as my invention, and desire to secure by Letters Patentin a meter for .measurin g water, is-

1. In a water-meter, the combination, with cylinder A, side pipe, B,openings 0 E D, and chest I", of the detached piston-head J,substantially as herein described.

2. In a water-meter, the combination, with cylinder A, side pipe, B,chest F, and detached piston-head J, of the disconnected piston-rods NN,frame 0, arm I and slotted quadrant S, for operating the weight Q,substantially as herein described.

3. In combination with the rods N N, frame 0, arm I, and slottedquadrant S, the curved lever T, cog-rack \V, arm A, shaft I, and arm H,for operating the slidevalve G, substantially as herein described, andfor the purpose set forth.
